Off topic, but only by a little for anyone trying cases:
Former DC police detective Jim Trainum tells reporter Saul Elbein about how his first murder investigation went horribly wrong. He and his colleagues pinned the crime on the wrong woman, and it took 10 years and a revisit to her videotaped confession to realize how much, unbeknownst to Jim at the time, he was one of the main orchestrators of the botched confession. (28 minutes)
Not to say every confession requires a “false confession expert,” but the story is a good cautionary tale and a solid dose of reality.
